| 摘 要： | 以新疆伊犁特大桥为工程背景,利用ANSYS有限元软件建立悬臂施工阶段箱梁的温度场仿真模型,对箱形梁桥施工过程中温度效应进行计算与分析,得到桥梁在不同时刻温度场作用下的应力及线形变化,并与现场试验数据进行对比,验证了该温度场仿真模型的正确性,得出一些温度效应对大跨度钢筋混凝土箱梁桥施工的影响规律。

| Abstract: | Backgrounded by the Ily Bridge in Xinjiang,the ANSYS finite element software is used to establish a simulation model for temperature field of a reinforced concrete box beam bridge at cantilever construction stage.The temperature effect of the box beam bridge during construction is calculated and analyzed,and the variations of stresses and geometric shapes of the bridge under the action of the temperature field at different time are obtained and compared to the measurement data of filed tests.The correctness of the simulation model is also verified and the laws of influence of the temperature effect on long span reinforced concrete box beam bridges have been concluded. |
